Anyone know what brand/manufacturer these are?
No name on them that I've found. Trying to figure out which oil psi sender I need

Do you have a decade box?

Negative. I'll have to ask around and see if I can locate one. Otherwise, May be putting the old gauges back in

You can buy a box of resistors in different resistances for about $5.

Power up the gauge and keep shorting from negative to "S" until the needle moves to the highest number on the gauge face. This is the sender resistance value.

I think I know which one you need, but need to check the catalog.

Any particular resistance to start with?

Thanks Glenn. May as well check water temp while I'm at it too

Sorry. Typo. 80 ohms. Then step down towards 42 ohms.

they look like the same gauges we have in the bahner. Teleflex marine. Bought ours at bass pro.

Use stock GM sending units btw

I'll have to check. Tried to look one up on O'reillys site and it shows a 3 wire sender

Tried another sender and gauge works backwards. Was only able to find 68 ohm and 47 ohm resistors.
68ohm got me to 60psi on the gauge.
47ohm got me to 70 psi. I did put a mechanical gauge in to verify, 70 psi at idle.
Any idea is appreciated

Lol Drew. I won't push for knowledge.

Did you get that spectra?

So if I'm figuring this right, looks like I'll need a sensor with a 240-33 ohm range?

Does 240-33ohm sound correct?

Sort of.

I am hanging at the shop. Let me poke around for a second.

Standard Stewart Warner sender.

Should be part number 279A or equivalent.

Much appreciated! Learned something new.
All I was able to locate local was a VDO equivalent. Should have it tomorrow
